1. The wings are missing in mutant fly L, which is likely the result of a mutation in________ .
2. Mutant fly X has lost the head and thorax. The gene most likely responsible for this mutation is____________.
3. Thoracic and abdominal structures are missing in mutant fly Q. The gene most likely responsible for this mutation is__________ .
4. Mutant fly F has predominantly lost abdominal structures, which is likely the result of a mutation in _________ .
5. The mutation observed in mutant fly O resulted in defects within the anterior or posterior regions of each segment. The gene that most likely caused this mutation is _________.
6. Segment-sized sections of every other segment are missing in mutant fly Z. One likely candidate gene is ________
a. hunchback (a gap gene)
b. even-skipped (a pair-rule gene)
c. wingless (a segment-polarity gene)
d. knirps (a gap gene)
e. hedgehog (a segment-polarity gene)
f. Kruppel (a gap gene)
Answer:
1.wingless (a segment-polarity gene)
2. hunchback (a gap gene)
3. Kruppel (a gap gene)
4. knirps (a gap gene)
5. hedgehog (a segment-polarity gene)
6. even-skipped (a pair-rule gene)
Explanation:
The gap genes are genes expressed during embryonic development of some arthropods. Loss of function mutations of the gap genes are responsible to produce structural "gaps" in the corresponding region of the embryo. The gap genes are transcription factors that modulate the expression of pair-rule genes, which in turn are required for embryonic development of the alternate segments. On the other hand, the segment polarity genes are involved in determining the anterior/posterior axis of each segment (the segment polarity network). In the embryo, segment-polarity genes are expressed at specific localizations only after the expression of gap and pair-rule genes.
The relative value of grains for animals is determined primarily by metabolizable energy and crude protein content. From the information below, which grain is the best choice for feeding swine?Grain Crude Protein Metabolizable Energy $ Per TonBarley 13.00% 3.000 kcal/kg 170Corn 10.00% 3.600 kcal/kg 160Grain sorghum 12.00% 3,200 kcal/kg 140Wheat 14.00% 3,400 kcal/kg 180
Answer:
Corn
Explanation:
Good news for corn and soybean hog growers because these two grains are the main ingredients in pork diet and these feedstuffs should be affordable. According to metabolism, corn has the highest metabolic energy, i.e. 3600 k.cal/kg Therefore, corn is the best food for swin so, the correct answer is corn.The first place that the reabsorption of water is not automatically coupled to the reabsorption of filtered solutes occurs in the PCT.
a. True
b. False
Answer:
False
Explanation:
The correct answer is false because Reabsorption of water and other filtered solutes like vitamins, sodium e.t.c. take place in the proximal convoluted tubules.
Reabsorption is when water and solutes in the PCT are removed and moved back into the blood and it's a process that take place through bulk transport.
The solutes and water are transported from the PCT to the interstitium and then move into peri-tubular capillaries and reabsorption in PCT is isosmotic i.e solutes have the same osmotic pressure.

Where does that air go as a result?
Answer:
Air go from one place to another due to difference in temperature of land and sea.
Explanation:
Air go as a result of wind from one place to another. Air moves from land to sea is called land breeze and from sea to land is known as sea breeze. This will occur when there is difference in temperature between sea and land. Sea breeze occurs at afternoon while land breeze occurs at night till morning. Warm air produces low pressure and cold air produces high pressure so when warm air rises, cold air takes its place and this cycle continues.

what are some questions an environmental biologist might ask about qhat they are studying
in the fruit fly, the long wing allele is dominant over the short wing allele. What are the parental genotypes for a cross that yields 75% long winged offspring and 25% short winged offspring.
According to the scenario, the parental genotypes for a cross that yields 75% long-winged offspring and 25% short-winged offspring are Ll and Ll.
What are Genotypes?Genotypes may be defined as the ultimate combination of alleles of those genes which are significantly taken for specific studies.
According to the context of this question, in the fruit fly, the long-wing allele is dominant over the short-wing allele. This means that capital L is dominant over small l. So, the genotypes LL and Ll govern the dominant trait, i.e. Longwing.
The Punnett square for the given cross is as follows:
Therefore, the parental genotypes for a cross that yields 75% long-winged offspring and 25% short-winged offspring are Ll and Ll.

A researcher discovers that polar bears have very good insulation and very think hair (similar to pandas). However, they do not show the rest of the panda behaviors. For example, they have high daily energy expenditure and are very active. Why are the panda and polar bear so different
Answer:
Panda and polar bear have some similar characteristics but they also have differences in their behaviors such as polar bears have high daily energy expenditure and are very active while pandas are not.
The panda and polar bear so different because of the geographical difference where they live.
Polar bears are marine mammals and live in north pole perform swimming in north oceans and also move on ice flows, where they catch seals for survival, it makes them active and energetic.
While Pandas are found in China bamboo forests and are herbivores. They eat leaves from bamboo trees, for which they do not require to be more active and get their food easily. So, Pandas are not active as polar bears.
As the climate of North pole and China is cold, both polar bear and panda have very good insulation

Which of the following correctly describes the process of Translation?
I. tRNA anticodon bonds to mRNA codon
II. Ribosome bonds to mRNA strand
III. Ribosome reaches a STOP codon and detaches from the mRNA
IV. Each tRNA adds an Amino Acid to the chain as the Ribosome moves along the mRNA
V. Complimentary mRNA strand is made from DNA template
Answer:
I. tRNA anticodon bonds to mRNA codon
II. Ribosome bonds to mRNA strand
III. Ribosome reaches a STOP codon and detaches from the mRNA
IV. Each tRNA adds an Amino Acid to the chain as the Ribosome moves along the mRNA
Explanation:
Translation is the second process of gene expression in which a protein molecule is synthesized from the information in a mRNA strand. Translation occurs in the RIBOSOME (an organnelle for protein synthesis made up of ribosomal RNA (rRNA) and proteins). The process of translation occurs in three stages viz: Initiation, Elongation and Termination.
Initiation occurs when the ribosome binds to the mRNA strand in the cytoplasm. The mRNA sequence is then read in a group of three nucleotides called CODON by the ANTICODON of a transfer RNA (tRNA). The basis of reading is the complementary base pairing rule i.e. A-U, G-C. Options I and II describes this stage.
In the elongation stage, the tRNA carries an amino acid corresponding to what it reads in the mRNA codon to the growing polypeptide chain. The amino acids bonds to one another via a peptide bond. As each codon is being read, the mRNA gradually moves over the means sequence. Option IV describes this stage.
Elongation stage continues until any of the stop codons (UAA, UAG, and UGA) are finally encountered by the trans in the ribosome. Since, there are no corresponding anticodons that can read the stop codons, they signal the termination of the translation process. The ribosome then detaches from the mRNA sequence. Option III describes this stage.
Note, option V describes TRANSCRIPTION not TRANSLATION.

This question is incomplete because there are no options; here is the complete question:
Bats have oversized ears, which help the bad you sound waves to detect the motion of their prey which example of the characteristics of life is most similar
A) A yeast cell splits itself in half to create a new organism.
B) A rat hides in its hole when it sees an approaching predator.
C) A fungal cell releases carbon dioxide back to the atmosphere.
D) A human child grows taller every year.
The answer to this question is B) A rat hides in its hole when it sees an approaching predator.
Explanation:
One of the characteristics of living organisms is the ability to adapt or respond to the environment. This feature of life is the one shown by bats in this case because the oversized ears are a result of evolution and adaptation that help bats to have more chances of survival. Similarly, rats hiding to avoid predators is a result of adaptation that helps rats survive by avoiding predators. Thus, rats and bat show the same characteristic of life.
